The argument 1 to the call of exit enables the system to provide an error code which gives an indication of the problem The next few lines of code create the required streams to let us read from the socket When these lines of Java are executed, we already have a connection established from a client We know this because the call to accept() blocks execution until this is true In this example, we have chosen to use a BufferedInputStream from the javaio package We have to catch the exceptions because the call could generate a problem The alternative would be to declare that our class can throw the same exception, but this approach has the cost of losing the resolution which is provided by catching exceptions at the point in the code where they are thrown If the application has successfully created the ServerSocket, accepted an incoming connection request and dealt with the I/O streams, we can then read a line of input from the socket connection This line of input will be the line that the user has typed We have defined a separate method called getline() to handle this task In essence, getline() reads a byte from the stream we have associated with the socket (it is not possible to read and write directly to sockets instead you must associate a stream using the getInputStream() and getOutputStream() methods) If the byte is equal to 1 then there is no input from the user waiting to be read If the byte is not equal to 0, then we make a cast from the integer value of the byte to a char and place the character into a StringBuffer When the character matches "\n" (which is the code for the return key) we send back the String representation of the StringBuffer At this point simpleServer prints out the line that getline() returned and since there are no other lines of code to execute the application exits 833 Extending the server The first example has illustrated the basics of writing a very simple server The first step is to create a ServerSocket which will be used to accept incoming connections The next stage is to accept a connection on the ServerSocket and to process the input appropriately In our example we just used the standard telnet to test out the server and typed in strings from there We will come to writing clients later in this chapter So, we now can write lines to the server out channel but what about the client Also, what happens if we want to deal with more than one line of text The next example covers both these cases Because we are going to handle multiple lines of text, we ll also add support so that the user can type bye-bye to terminate the connection The constructor for simpleServer has the following lines to supervise reading the line and printing it out The rest of the constructor remains the same with getline() still being used to handle reading from the connection /* Read line from the socket and then write it out */ do { str = thisgetline(); thisputline("You said: " + str); Systemoutprintln("Str: " + strtrim()); } while (!strstartsWith("bye-bye")); The first change is that we are now using a do-while loop to handle reading from the connection As long as the string returned from getline() does not start with "bye-bye" then the loop keeps reading lines of text When the string does start with "bye-bye" the loop is terminated and the application exits since there is no more code to execute We have also added a new method to handling writing strings to the client, called putline() The Java code for this is: public void putline(String line) { byte tline[] = new byte[1024]; linegetBytes(0,linelength(),tline,0); try { conngetOutputStream()write(tline,0,linelength()); }.

In Listing 616, InternationalAddress inherits from Address and implements ToString() To call the base class's implementation you use the base keyword The syntax is virtually identical to this, including support for using base as part of the constructor (discussed shortly) Parenthetically, in the AddressToString() implementation, you are required to override as well, because ToString() is also a member of object Any members that are decorated with override are automatically designated as virtual, so additional child classes may further specialize the implementation

In many instances, particularly when dealing with low-level or system services, information is retrieved as binary data In order to manipulate these devices and services, you need to perform manipulations of binary data

When instantiating a derived class, the runtime first invokes the base class's constructor so that the base class initialization is not circumvented However, if there is no accessible (nonprivate) default constructor on the base class, then it is not clear how to construct the base class and the C# compiler reports an error To avoid the error caused by no accessible default constructor, programmers need to designate explicitly, in the derived class constructor header, which base constructor to run (see Listing 617)

Consider the ColumnValues property implementation on the Contact class This member is not an integral part of a Contact type but a peripheral member probably accessed only by the ConsoleListControl class As such, it doesn t make sense for the member to be immediately visible on a Contact object, cluttering up what could potentially already be a large list of members Alternatively, consider the IFileCompressionCompress() member Including an implicit Compress() implementation on a ZipCompression class is a perfectly reasonable choice, since Compress() is a core part of the ZipCompression class s behavior, so it should be directly accessible from the ZipCompression class

Consider an ITrace interface with a member called Dump() that writes out a class s data to a trace log Implementing Dump() implicitly on a Person or Truck class would result in confusion as to what operation the method performs Instead, it is preferable to implement the member explicitly so that only from a data type of ITrace, where the meaning is clearer, can the Dump() method be called Consider using an explicit implementation if a member s purpose is unclear on the implementing class
